- ful Improvements in Vapor-Burners, ot' which the following is a specification.

This invention relates to improvements in vapor-burners in which the burner proper and the vaporizing-chamber areformed in one piece; and the objects of my improvements suitableform to produce an increased efficiency ot' action.

The invention consists in giving to the tube bringing the hydrocarbon to the burner the form of an arch passing over and among the jets of flame that may issue from the burner, and in making said arched tube integral with the burner, and other means, as will be hereinafter described, and pointed out in the claims.

Heretot'ore in vapor-burners the pipe leading from the oil-reservoir has often been made to pass over the liame of the burner, either eX-v posed at adistance therefrom or protected with a casting secured to the under side thereof, or the oil has been made to circulate through rectangular passages made vertically or horizontally around the walls of the burner; but in every case the form ot' the reservoir for lthe heated vapors produced differs from mine.

In the drawings, Figure 1 represents a perspective view of the burner. Fig. 2 represents a longitudinal vertical section, and Fig. 3 a transverse vertical section, of the same.

In said drawings, A represents the semispherical portion of the burner. It is cast in one piece with a short cylindrical top, A', and

each portion is provided with a series ot' perforations, a, for the passage of the inflammable vapors. The burner A Al is also provided with anarched vaporizing-chamber, A2, cast with it, so that its upper portion projects above the portion A and tap A of the burner, and

its under portion is within the burner and top thereof, so as to receive the full benefit of the latent heat communicated to the burner from the flame surrounding it when in full operation. The arched form of the vaporizin g chamber or tube A2 materially assists its action, as it retards the advance of the oil, and forces it to present a large surface at the point where it becomes transformed into vapor by the latent heat of the burner. The burner A has its bottom closed by a circular plate, B, having its edge preferably rabbeted to lit the bottom edge of' the bnrnerA,the two being united together by a4 couple of pins, c, passing under the plate B, through pendent lugs a2 formed on the bottom edge of the burner A, the rabbeted edge being cut away on opposite sides for the passage of the lugs. are simplicity of construction, combined with a Through the bottom plate, B, and preferably formed in one piece therewith, passes the pipe B', the upper part ot' which projects vertically within the cavity of the burner-cap. Thelower end of the pipe B is bent to one side, and is expanded at B2 to form a somewhat funnelshaped mouth, and terminates in an elongated cup, B2, adapted to receive a burning-liquid.

' To the. under side of the plate B is secured the cup C, so as to project under the iinidreceiving end of the vaporizing-tube A2. This cup C is to receive alcohol or other inflammable fluid. The vapor-conducting end of the vaporizing-tube kA2 has a hollow stopper, D, provided with a small conical perforation, d, on one side, that is controlled by an ordinary pointed conical valve or needle, c, at the end of a stem, E, provided with a hand-wheel, E.

In using this burner any suitable liquid is received in the tube A2 in the direction of the arrow shown in Fig. 2, from a pipe connected with a reservoir, said pipe containing usually coiled Wire-netting, fine gravel, &c.,to prevent the uid contained therein from flowing too rapidly toward the burner. To start the apparatus properly it is rst necessary to transform into vapor a portion of the fluid in the tube A2, so as to have nothing but hydrocarbon vapors contained therein. This is accomplished by rst heating sufficiently said tube A2, either by means of alcohol burning in the cups B3 and O, (and this is the means that I prefer,) or by allowing a small quantity of the liquid contained in the tube A2 to issue into the cup B3 and iniiaming it; but I have found that it is better to heat both ends of the tube A2 by using alcohol at the same time in the cup C. After a sufficient time has elapsed to heat the tube A2 and vaporize its contents the needle-valve e is opened, and a jet of hot vapor is projected through the open mouth of the pipe B with a IOO current of air wit-hin the interior of the burner, from which it immediately escapes through the openings a, and is lighted with a match on the outside thereof. The flames thus produced soon lbring the whole of the burner-top to a high temperature, and the vaporizing chamber or tube A2, being made in one piece with said burner-top, continues at a high temperature While the burner is in use, and produces a constantsupplyofintlaniinablevapors. Thearched form of the tube A2 is very appropriate for a vaporiziug-chaniber, forming at the saine time a sort of trap containing vapors to arrest 'the liquid before it reachcsthe center of the burner.

The cups B3 and G may be formed in one piece independently of the pipe B', and be connected by a channel, Cf, as shown by dotted lines in Fig. 2, said cups and channel being` then secured to a lug, b', pendent from said pipe B, and thus it will not be necessary to pour alcohol or other burning-fluid at two points to start the burner in operation.

Having now fully described my invention, I claiin- 1. A vapor-burner consisting of a hollow cap, with a tubular arched vaporiZing-chamber cast therewith in one piece and passing over` and across said cap, substantially as and for the purposes described.

2. The combination of a perforated hollow cap, a tubular arched vaporizing-chamber passing over and diametrically across said cap, with a bottoni plate, B, having a central pipe bent to one side and provided with a cup, substantially as and for the purpose described.

3. The combination ot' a perforated hollonr cap, a tubular arched vaporizin g-chamber passing over and diametrically across said cap, and a hollow stopper, D, having an opening, d, on one side thereof, with a bottom plate, B, having a central pipe bent to one side and provided with a funnel-shaped opening, B2, and a cup, B3, substantially as and for the purposes described.

4. The combination of a perforated hollow cap, a tubular arched vaporizing-chamber passingover and diainetricallyacross said cap, with a bottom plate having a central pipe bent to one side and provided with a cup, B3, and a cup, C, secured under the fluid-receiving end of the vaporizing-chainber, substantially as and for the purpose described.
